The light-cone nature of PDFs, GPDs, and TMDs makes them directly inaccessible from lattice QCD that is based on a Euclidean metric. However, the development of approaches other than Mellin moments has led to a successful research program to obtain the \(x\) -dependence of distribution functions from lattice QCD. A widely used approach is based on calculations of matrix elements of non-local operators and boosted protons, the so-called quasi-distributions method. Such matrix elements are then related to the light-cone distributions via Large-Momentum Effective Theory (LaMET) [1]}. Extensive reviews of the various approaches to get \(x\) -dependent distribution functions can be found in Refs. [2]}, [3]}, [4]}, [5]}.
